UnDBX is a tool to extract e-mail messages from Outlook Express .dbx files.
On first invocation all messages will be extracted as individual .eml files. Subsequent invocations will only update the output directory. Any .eml files that do not correspond to messages in the .dbx file will be treated as deleted messages and will be deleted from the disk. Furthermore, only new messages, that do not correspond to files on disk, will be extracted from the .dbx file.
UnDBX was written to facilitate fast incremental backup of .dbx files.
There’s no installer or setup program. Simply extract the distribution .zip file to some folder.
